IMPRQVEMENT IN TIME-INDICATORS FOR OFFICES.

The Schedule referred to in these Letters Patent and making part ofv the lsame.

I, EDWIN A. WOOD, of the city of Utica, county of Oneida and State of New York,have invented an Improved Otce Hour-Dial, of which the following is a specification.

'Nature and Objects of the Intention.

The instrument is designed. to vreport the hour of attendance at his office of any particular person, for the information of those who may cali there during ,his absence.

Description of the Accompanying Drawing.

Figure 1 represents a front, and

Figure 2 a sectional view of the instrument; and

Figure 3, sheet No. 2,'a sectional -view of the dial showing a raised collar, G, on an enlarged scale.

A is the case.

B, an ordinary clock-dial.

C, a glass covering the same.

D, an opening in the dial, cut out on three sides and pressed back, making a clip, in which a card may be inserted' from the back and read from the front of the dial; Or two parallel slits may be cut in the dial and the card passed through them in the same way and with the like effect.

E and El are hour and minute-bands.

E2, a pin in th hour-hand, by which it is moved when the minuteiaud comes in Contact with it; or, instead of' a pin the point of the hour-hand may be turned up.

F, a spindle with a knob or other means by which the minute-hand may be turned around the dial from the back of the case.

G, a collar punched up or raised around the center hole-of the dial, on which the hour-hand is placedI and From the foregoing it will be seen that the instrument consists of an ordinary clock-dial with hour and minute-hands protected by a glass iu the ordinary Way, thelhands being movable from the back of the dial, and so constructed as to be set at any particular hour desired, with an openingpin the dial for the purpose of showing on a card or other material the name of the individual using it,.and with the words will return at printed or engraved ou the face of the dial.

.The instrument is used hy setting the hands to the particular time when the individual absenting himself intends to return, and placing it iu some conspicuous place Where callers may see it.

vI do not confine myself to the opening with a clip, as it may be left entirely open and'a card be fastened to the back of the dial in some other way and read from the front through the opening; or the card may be inserted through parallel slits out in the dial; but

What I claim as new,- and desire to secure by Letters Patent, is-

Forming a raised sleeve around the center hole of the dial, on which one of thehands is secured and revolves, the other being attached to a spindle ruiming through the center hole.
